test: Use INFINITY & NaN for intermediate metrics

As MIN_VALUE is the smallest positive value IEEE 754 allows,
computeStats() returns an incorrect maximum value when it receives a set
of metrics that are all 0 so replace MIN_VALUE with NEGATIVE_INFINITY.

For consistency and clarity, use the corresponding POSITIVE_INFINITY and
NaN to respectively initialize the minimum value and median value; as
the function assumes that it received at least one item by dividing by
(values.size() - 1), these values should never be returned by the
function.
